- Who did first use the term "simple" in group sense? More appreciated if I learn the original word(might be in French, Galois???)...
and also...
- Why do you think that this term is chosen etymologically? A meaning of "ease"?(To me, sounds not plausible) Or, a sense of "being core/atom"?(Just a guess!)
P.S. This question might contribute a better perspective of simple groups for me and whoever reads here.
