(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A246501 a(n) is the smallest term of A242719 that is repeated exactly n times, or 0 if there is no such term. 2

COMMENTS

We conjecture that, for all n, a(n)>0.

Integer parts of sqrt(a(n)-1) are 3,13,61,291,523,3001,1913,4793,... (as for all terms of A242719, if a(n)-1 is perfect square, then sqrt(a(n)-1) is prime).
