1,1

Sequence computed by Mensanator. The "tail" of the sequence is made from its last four terms. This is the longest possible such sequence.

Table of n, a(n) for n=1..32.

Erasing the last digit of every term of 2 3 5 7 23 37 59 73 leaves 2 3 5 7 which is 2 3 5 7 23 37 59 73 without its "tail" (the last four integers)

Cf. A024770, Right-truncatable primes: every prefix is prime.
