A095782 Values of n for which A095777(n) is 13 (those terms which are expressible in decimal digits for bases 2 through 14, but not for base 15). 0
14, 28, 29, 42, 44, 56, 57, 72, 73, 74, 85, 86, 100, 104, 196, 198, 199, 200, 201, 204, 210, 211, 212, 213, 216, 217, 224, 253, 254, 295, 392, 393, 396, 397, 398, 399, 434, 435, 436, 437, 438, 448, 449, 462, 463, 464, 507, 508, 509, 520, 521, 522, 523, 524 (list; graph; refs; listen; history; text; internal format)

LINKS

Table of n, a(n) for n=1..54.

EXAMPLE

a(5)=44 because 44 when expressed in successive bases starting at 2 will produce its first non-decimal digit at base 15. Like so: 101100, 1122, 230, 134, 112, 62, 54, 48, 44, 40, 38, 35, 32. In base 15, 44 is 2E.

MAPLE

S := []; for n from 1 to 2000 do; if 1>0 then; ct := 0; ok := true; b := 2; if (n>9) then; while ok=true do; L := convert(n, base, b); for e in L while ok=true do; if (e > 9) then ok:=false; fi; od; if ok=true then; ct := ct + 1; b := b + 1; fi; od; fi; if ct=13 then S := [op(S), n]; fi; fi; od; S;
