    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:

    Primonacci numbers: a(n)=a(n-2)+a(n-3)+a(n-5)+a(n-7)+a(n-11)+...+a(n-p(k))+... until n > p(k), where p(k) is the k-th prime. a(1)=a(2)=1. oeis.org/A078465 Is a(n)=A276420(2*n)? sequencedb.net/?s=A078465

    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)

    Bonse sequence: a(n) = minimal j such that n-j+1 < prime(j). oeis.org/A060646 Is a(n)=A036234(1+n-a(n-1))? sequencedb.net/?s=A060646

    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.

    uClassify was having connection issues for the past 3h. I think I found the problem. I will monitor the server closely during the day. Sorry for the inconvenience.
