Some finite solvable groups with non-trivial lattice endomorphisms
The main purpose of this paper is to exhibit a doubly-infinite family of examples which are extensions of a p -group by a p ′-group, with the action satisfying some conditions of Zappa (1951), arising from his study of dual-standard (meet-distributive) subgroups. The examples show that Zappa's conditions do not …
