COMMENTS

For any positive base B >= 2 the corresponding sequence contains only terms from 2 to B inclusive so the corresponding sequence for binary is all 2s (A007395).

EXAMPLE

a(12)=9 as 12 has two decimal digits and 9*12=108 has three (but 8*12=96 has only two).

CROSSREFS

Cf. A089186 (analogue for decimal m+n), A080079 (analogue for binary m+n), A097326 (A097327 - 1).

Sequence in context: A134167 A080461 A066578 * A007272 A061280 A030071

Adjacent sequences:  A097324 A097325 A097326 * A097328 A097329 A097330
