See A237600 for a complete list of right-truncatable primes in base 16.

Right-truncatable means that the integer part of successive divisions by 16 yields again primes (or zero). There are no such numbers with more than 14 digits in base 16. - M. F. Hasler, Nov 07 2018

EXAMPLE

The largest right-truncatable prime with 8 hex digits, written in hex notation, is DF33F3FF (in decimal, 3744723967).

PROG

(PARI) See the link (use GT_DivMod0 with arguments "isprime" for "property" and 16 for "b").

(PARI) A237602=vector(14, n, p=concat(apply(t->primes([t, t+1]*16), if(n>1, p))); p[#p]) \\ Only the largest term is needed, but we keep all of them since we don't know which will produce "successors". - M. F. Hasler, Nov 07 2018
