%C Number of terms below 10^k for k = 6, 7, ... 10: 19, 231, 2111, 22426.

%C The first occurrences of 2 consecutive pairs of twin weirds are (21607670, 21607672, 21608090, 21608092), (873951608, 873951610, 873951890, 873951892), ...

%H Amiram Eldar, <a href="/A306952/b306952.txt">Table of n, a(n) for n = 1..22426</a> (terms below 10^10).

%e 512468 is in the sequence since both 512468 and 512470 are weird numbers.

%Y Cf. A006037, A125109, A231086 (supersequence), A231964.
