To all category theorists: While (partially) responding to Tom Leinster's 7/04 query regarding limit preservation, a query of my own occurred to me: On pages 6 and 7 of Alain Connes' book, "Noncommutative Geometry", he writes, "It is fashionable among mathematicians to despise groupoids and to consider that only groups have an authentic mathematical status, probably because of the pejorative suffix oid." Professor Connes later cites the groupoid of states of the hydrogen atom in order to eliminate the prejudice against groupoids, but, for group theorists, there is a more direct way: Since Frobenius and/or Burnside adopted the concept of an abstract group in order to consider general group actions and representations, group theorists have been heavily involved in groupoids, whether they liked it or not. Is it generally understood by categorists that every group action---as a comma category---is a groupoid? Pat Donaly
