This article does not define its subject (cyclically ordered group). This is a big no-no. — Preceding unsigned comment added by 2001:62A:4:2F00:6E0B:84FF:FEA5:6CA7 (talk) 14:24, 21 August 2019 (UTC)
Unclear writing edit
The section The circle group begins as follows:
"Świerczkowski (1959a) built upon Rieger's results in another direction. Given a cyclically ordered group K and an ordered group L, the product K × L is a cyclically ordered group. In particular, if T is the circle group and L is an ordered group, then any subgroup of T × L is a cyclically ordered group. Moreover, every cyclically ordered group can be expressed as a subgroup of such a product with T."
But the article doesn't even give a hint as to how one obtains a cyclic ordering on the product K × L.
