Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N a(1) = 4, a(n) = smallest number of the form k*a(n-1) +1 with the same prime signature p^2, where p is a prime.
%C a(8) = (28*A(7)+1)^2, which has 108 digits and is too large to include. - _David Wasserman_, Jan 11 2005
%Y A061092 gives the sequence with a(1) = 2 i.e. terms of the form k*a(n-1)+1 which are primes.( prime signature p^1)
