Omega (ω) is the first transfinite ordinal. This means that it's the smallest infinity, it comes after all the natural numbers. (Non fictional).
Regarding the number base n, the omega number is simply (n − 1). The factors tα > 2 of (n − 1) are called alpha factors in this work. These factors are integers necessarily coprime to n, but have the brief minimum period 1. In base n, ω = (n − 1) is always written as the largest digit or (natural) numeral of the base, assuming standard positional notation and Hindu-Arabic-like numerals.
