 A068183 Largest number without decimal digits equal to 1, whose product of digits gives n!. 10
 2, 32, 3222, 53222, 5332222, 75332222, 75332222222, 7533332222222, 755333322222222 (list; graph; refs; listen; history; text; internal format)
 OFFSET 2,1 LINKS FORMULA a(n)=Max{x; f[x]=n!}, where x has no digit=1 and f[x_] := Apply[Times, IntegerDigits[x]]. EXAMPLE Maximal solutions are obtained from concatenation of distinct all prime-factors which has one decimal digit. The sequence is finite because n! for n>10 has 2-digit prime-factors.
