Theorem ttceqi

Description: Equality inference for transitive closure. (Contributed by Matthew House, 6-Apr-2026)

	Ref	Expression
Hypothesis	ttceqi.1	$$⊢A=B$$
Assertion	ttceqi	Could not format assertion : No typesetting found for |- TC+ A = TC+ B with typecode |-

Proof

Step	Hyp	Ref	Expression
1		ttceqi.1	$$⊢A=B$$
2		ttceq	Could not format ( A = B -> TC+ A = TC+ B ) : No typesetting found for |- ( A = B -> TC+ A = TC+ B ) with typecode |-
3	1 2	ax-mp	Could not format TC+ A = TC+ B : No typesetting found for |- TC+ A = TC+ B with typecode |-
