4 8 15 16 23 42This is the first six letters of the fictimeric sequence beginning with 4. The fictimeric sequence beginning with n is defined as n, 2n, 4n-1, 4n, 6n-1, followed by the fictimeric sequence for 11n-2. In a comment, I gave the last term incorrectly as 13n-1, obviously not because I can't multiply but because I was temporarily confusing the fictimeric sequence with the fictimetric sequence.
The fictimetric sequence is the sequence formed by the fictimetric operator used to measure fictionerous spaces. The function fict(n) is defined as follows:
fict(1) = 1The theory of fictionerous spaces and fictimetric and fictimeric numbers is a fairly recent development in number theory, being only about ten minutes old. It was developed in order to explain peculiar numerical postings on certain simian weblogs and to justify errors that various mathematically-inclined people might have made in the comments to such postings.
fict(n) = 2n-1 (n prime)
fict(n) = 3n-1 (n even and n/2 prime)
fict(n) = 5n-1 (n mod 3 = 0 and n/3 prime)
fict(n) = 7n-1 (n mod 5 = 0 and n/5 prime)
fict(n) = 11n-1 (n mod 7 = 0 and n/7 prime)
fict(n) = 13n-1 (otherwise)
