From each odd square starts a new run of odd terms in A259934 (see A262516 for the lengths of these and A262517 for the odd terms themselves), which lasts as long as the next even square is encountered, at which point the parity of terms is switched back to even. %C A262514 The terms were grepped from the data file of A259934 provided by _Max Alekseyev_, which contained terms up to A259934(397420670) = 9999999974. %C A262514 The indexing starts from zero, because a(0) = 0 is a special case in this sequence. %C A262514 a(31) > 10^16. - _Hiroaki Yamanouchi_, Oct 07 2015 %H A262514 Hiroaki Yamanouchi, <a href="/A262514/b262514.txt">Table of n, a(n) for n = 0..30</a> %F A262514 a(n) = A259934(A263276(n)). %Y A262514 Cf.
