ants! i am so glad you came back! and posted again! we are a wild and crazy bunch-- and as you have noted, are prone to as you so gallently worded it..intriguing diversions. Welcome to board.. and do please stay, and post.

as for the answer to your question, its greek to me.. i only have a second class degree.. (but not a desmond..) which i am sure Jackie's aunt Mav or Rhu will be happy to explain. so no latin or greek for me. but as i recall the prefixes are not too different.. deca is 10 (as in a dodecahedron-- a 12 sided figure.. (do =2, deca=10, dodeca=2+ 10 or 12) but i don't specifically know the numeric prefixes.

and keep plugging away, we will continue to spin off diversions. but eventually, we will answer your questions..
