Nuprl Lemma : igrp_properties
∀[g:IGroup]. Inverse(|g|;*;e;~)
Proof
Definitions occuring in Statement :
igrp: IGroup,
grp_inv: ~,
grp_id: e,
grp_op: *,
grp_car: |g|,
inverse: Inverse(T;op;id;inv),
uall: ∀[x:A]. B[x]
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
igrp: IGroup,
imon: IMonoid,
sq_stable: SqStable(P),
implies: P ⇒ Q,
squash: ↓T,
inverse: Inverse(T;op;id;inv),
and: P ∧ Q
