Every term in the sequence begins with the digit 6.

LINKS

Table of n, a(n) for n=1..35.

EXAMPLE

The prime 611833 is in the list because 118336 = 344*344.

PROG

(PARI) rotl(a) = my(b, c, d); b=#Str(a); c=floor(a/(10^(b-1))); d=a-c*(10^(b-1)); 10*d+c

s=[]; forprime(n=2, 700000, if(issquare(rotl(n)), s=concat(s, n))); s
