Theorem madetsmelbas2 22354

Description: A summand of the determinant of a matrix belongs to the underlying ring. (Contributed by AV, 1-Jan-2019.)

**Hypotheses**
Ref	Expression
madetsmelbas.p	⊢ 𝑃 = (Base‘(SymGrp‘𝑁))
madetsmelbas.s	⊢ 𝑆 = (pmSgn‘𝑁)
madetsmelbas.y	⊢ 𝑌 = (ℤRHom‘𝑅)
madetsmelbas.a	⊢ 𝐴 = (𝑁 Mat 𝑅)
madetsmelbas.b	⊢ 𝐵 = (Base‘𝐴)
madetsmelbas.g	⊢ 𝐺 = (mulGrp‘𝑅)

**Assertion**
Ref	Expression
