Nuprl Lemma : sq_stable__grp_leq

∀[g:GrpSig]. ∀[a,b:|g|].  SqStable(a ≤ b)


Proof




Definitions occuring in Statement :  grp_leq: a ≤ b,  grp_car: |g|,  grp_sig: GrpSig,  sq_stable: SqStable(P),  uall: ∀[x:A]. B[x]
Definitions unfolded in proof :  grp_leq: a ≤ b,  uall: ∀[x:A]. B[x],  member: t ∈ T,  infix_ap: x f y,  implies: P ⇒ Q,  all: ∀x:A. B[x],  sq_stable: SqStable(P),  prop: ℙ
