This note proves the recurrence and rational generating function conjectured for OEIS A074003. The proof reduces the trace-and-subtrace conditions over GF(3^n) to a quadratic trace condition, evaluates the resulting character sum using quadratic Gauss sums and the Davenport-Hasse lifting formula, and derives …

We prove the conjectured trigonometric formula for the Kempner numbers (OEIS A002034). The proof uses the roots-of-unity filter to show that the cosine sum is the indicator of the divisibility condition n | m!.
