5322 procedurally generated conjectures for OEIS entries that do not yet have a formula field: sequencedb.net/index.html?s=!… Some more info here jonkagstrom.com/conjectures/in…

@sequencedb Also appears to be the position of zeros in the fixed point mapping 0->20, 1->20, 2->1120

a(1)=1; for n>1, a(n)=a(n-1)+4 if n is already in the sequence, a(n)=a(n-1)+2 otherwise. oeis.org/A080903 Is a(n)=A086398(n)-(A284751(n)+A284751(n))? sequencedb.net/?s=A080903

@sequencedb Actually the second formula looks more interesting: a(n)=eq[A210882(n), A235711(n)]

Interprimes (A024675) which are of the form s*prime, s=2. oeis.org/A075277 Is a(n)=2*A118134(n)? sequencedb.net/?s=A075277

@sequencedb Yes, submitted to the oeis (but for A242804)

Lesser of two semiprimes sandwiched each between semiprimes thus forming a twin semiprime-triple. oeis.org/A202319 Is a(n)=1+A242804(n)? sequencedb.net/?s=A202319

A comment in A078465 says: "a(n)/a(n-1) -> 1.476229...=1/x, where x satisfies the Sum x^p(n)=1 equation, i.e. x^2+x^3+x^5+x^7+x^11+... =1. (What constant is it?)" This relationship may add an interpretation in terms of the number of palindromic prime compositions of even n:

@sequencedb Yes obviously, but adding missing relation to the oeis.

Primes with odd digit sum. oeis.org/A119450 Is a(n)=p(A200260(n))? sequencedb.net/?s=A119450

I've setup a bot to tweet new interesting* mathematical conjectures that have been automatically discovered by sequencedb.net. (*timeline may contain traces of rubbish/trivial/obvious formulas)

@sequencedb Yes, this is just A223486 (Lucas entry points) of the n-th prime. Submitted formula and cf. Interestingly A223486 was added after A194363.

Lucas entry points: smallest m >= 0 such that the n-th prime divides Lucas(m), or -1 if there is no such m. oeis.org/A194363 Is a(n)=A223486(record[φ(1+n)])? sequencedb.net/?s=A194363

@cachri81 Yes that would be interesting!

@PMAN15655798 @abcoetzee @NurveNetworks Sorry I missed your message. I might do that in the future, if I ever get back to updating playchilla again (haven't touched it for a long time). But I will let you know if I do!

@jonkagstrom @abcoetzee @NurveNetworks That's right!I had many games by xtreme but I liked yours the best.I've been working on it for almost a month now, but I still can't get the game to work. I don't know much about programming, but would it be possible to take the link I showed you and put SpaceWorm on Playchilla?

@jonkagstrom I'm hoping that you are the same Jon Kagstrom who was lead programmer on one of my favorite games, Space Worm. I haven't been able to find any copies for the last 10 years. Any idea where I could find one?

@PMAN15655798 @abcoetzee That is incredible! It looks like it's from the CD/magazine, I remember I read that one could submit a game to Andre LaMothe, xtreme gaming (now @NurveNetworks it seems) and he might publish it. We even received a check or two :)

@jonkagstrom @abcoetzee cd.textfiles.com/100gg/Arcade%2… after a lot of searching, I found this, but there are problems. It's a .exe file, which I can't open on Mac, Windows 10 can't run 16-bit programs, and for some reason the program is sped up when I run it in a virtual machine

@abcoetzee @PMAN15655798 Indeed epic! Robin was very impressed that it was so exact the original. He also mentioned that it was improvised, I have a vague memory of him recording it on a really bad mic. Also I just recalled that one of the sfx is the modem connection sound, sped up 😀 long time ago now!

@PMAN15655798 @jonkagstrom Epic! What an amazing world we live in, where something as simple as a game or song can change lives around the world in profound ways.

@jonkagstrom check out the latest upload on my SoundCloud...I think you will enjoy it!

@abcoetzee @PMAN15655798 Look at that! Now I have the demo of our game :) thank you!

@jonkagstrom @PMAN15655798 Great game. I still listen to that amazing acoustic guitar tune. You can download the demo from the old website: web.archive.org/web/2014082919…

The music in the game was performed by my room mate Robin and the graphics by a fellow student Simon!

22 years ago I made a game called SpaceWorm, to my big surprise @PMAN15655798 remembers it and inspired him to start playing the guitar, check out his soundcloud: soundcloud.com/fourzero1.

@jonkagstrom 98 sounds right. My cousin put a copy on our computer when I was like, 4. It's the first video game I ever played. I know it's just snake, but the graphics, sound FX, and especially the music were just so cool to me. It's actually one of the reasons I Started playing guitar.

@PMAN15655798 Wow, it was my roommate who played the guitar and a fellow student who did the graphics. I will forward your kind words to them next time I talk to them! Is that you playing guitar on your soundcloud? It's amazing.

@geoffsdesk Not that I am aware off, if you email contact@uclassify.com with you username and describe the problem and I can take a look!
