Theorem odf1o1 19440

Description: An element with zero order has infinitely many multiples. (Contributed by Stefan O'Rear, 6-Sep-2015.)

**Hypotheses**
Ref	Expression
odf1o1.x	⊢ 𝑋 = (Base‘𝐺)
odf1o1.t	⊢ · = (._g‘𝐺)
odf1o1.o	⊢ 𝑂 = (od‘𝐺)
odf1o1.k	⊢ 𝐾 = (mrCls‘(SubGrp‘𝐺))

**Assertion**
Ref	Expression
odf1o1	⊢ ((𝐺 ∈ Grp ∧ 𝐴 ∈ 𝑋 ∧ (𝑂‘𝐴) = 0) → (𝑥 ∈ ℤ ↦ (𝑥 · 𝐴)):ℤ–1-1-onto→(𝐾‘{𝐴}))

Distinct variable groups: 𝑥,𝐴 𝑥,𝐺 𝑥,𝐾 𝑥,𝑂 𝑥, · 𝑥,𝑋

Proof of Theorem odf1o1 Dummy variable 𝑦 is distinct from all other variables.
