# Jordan called isomorphisms (iso.) and homomorphisms “iso. holoedriques” and “iso. meriedriques” respectively; translation of holoe/meried-driques?

Stillwell mentions in his Elements of Algebra:

The first to use the term "isomorphism" was Jordan, in his Traite des Substitutions [1870], the first textbook on group theory...Jordan used the word "isomorphism" for both isomorphisms and homomorphisms, but distinguished between the two by calling them "isomorphismes holoedriques" and "isomorphismes meriedriques" respectively.

What do the words holoedriques and meriedriques mean?

• As usual, they come from Greek : see here and this related post. – Mauro ALLEGRANZA Nov 22 '15 at 7:13
