 OFFSET 0,1 COMMENTS The famous Liouville number is defined so that its n-th fractional decimal digit is 1 if and only if there exists k, such that k! = n. The binary Liouville number is defined similarly, but as a binary number: its n-th fractional binary digit is 1 if and only if there exists k, such that k! = n. According to the definitions introduced in A092855 and A051006, this number is "the binary mapping" of the sequence of factorials (A000142). LINKS G. C.
