| Mar 13, 2021 at 9:57 | comment | added | Francois Ziegler | @ArnaldoMandel No, as already commented by Benjamin Steinberg that distinction may belong to groupoid (Brandt, 12 Dec 1925, p. 361): “Eine solche Menge miteinander verknüpfte Elemente soll Gruppoid heißen, wenn...” | |
| Mar 13, 2021 at 0:23 | comment | added | Arnaldo Mandel | First, thanks (not a thankoid) to all who answered. Still, the list presented in the answer above sort of reinforces my question, albeit slightly rephrased: Is "matroid" the first oid-named abstract structure? | |

| Mar 12, 2021 at 21:03 | comment | added | LSpice | Also, purely mathematically, a groupoid is not a quasi-group, I think. :-) | |
| Mar 12, 2021 at 21:03 | comment | added | LSpice | (I took '-oid' out of math mode; I hope that was OK.) I wouldn't have expected cuboid to be so late! The first ones that occurred to me were ellipsoid and spheroid; I wonder (but not enough to check) when they first occurred. | |
