plain-language theorem explainer

64 equals 2 to the sixth power and therefore carries exactly six prime factors counted with multiplicity, satisfying the predicate that marks a 6-almost prime. Number theorists maintaining arithmetic-function interfaces inside the Recognition Science codebase would cite the result as a verified base case. The proof reduces to a single native_decide call that evaluates the equality by direct computation.

Claim. $Ω(64) = 6$, where $Ω(n)$ counts the total number of prime factors of $n$ with multiplicity.

background

The module supplies lightweight wrappers around Mathlib arithmetic functions, beginning with the Möbius function. The predicate isSixAlmostPrime is defined directly as bigOmega n = 6. The upstream definition of isSixAlmostPrime encodes the 6-almost-prime condition via the big-Omega arithmetic function that tallies prime factors with multiplicity.

proof idea

The proof is a one-line term that applies native_decide to confirm that bigOmega 64 evaluates to 6.

why it matters

The declaration supplies a concrete base-case verification inside the arithmetic-functions module. It supports prime-related calculations that may later feed into Recognition Science constructions such as the phi-ladder or mass formulas, although no downstream use is recorded. It aligns with the framework's pattern of explicit computational checks for small integers.
