EXAMPLE

342 is in the sequence because 342 = 666 base 7.

685 is in the sequence because 685 = 1666 in base 7.

99968 is in the sequence because 99968 = 3666B in base 13.

CROSSREFS

Cf. A121205 is the numbers that in some base b are represented exactly as 666, so is a subsequence of this sequence.

Sequence in context: A204751 A247441 A045106 * A121205 A038852 A043419

Adjacent sequences:  A137198 A137199 A137200 * A137202 A137203 A137204
