 A237601 Number of n-digit right-truncatable primes in base 16. 11
 6, 16, 37, 60, 74, 77, 63, 39, 22, 11, 5, 2, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS See A237600 for a complete list of right-truncatable primes in base 16. LINKS Stanislav Sykora, PARI/GP scripts for genetic threads FORMULA a(n) = 0 for n >= 15. EXAMPLE a(2)=16 because there are 16 right truncatable hex numbers with two hex digits: 25,29,2B,2F,35,3B,3D,53,59,71,7F,B3,B5,BF,D3,DF. PROG (PARI) See the link (use GT_DivMod0 with arguments "isprime" for "property" and 16 for "b"). (PARI) A237601=vector(15, n, #p=concat(apply(t->primes([t, t+1]*16), if(n>1, p)))) \\ M. F.
