RE: Ho to calculate Pythagorean ....

Hi Bogdan,

> "2,3,5,7,12,17,29,41,53,94,147,200,253,306,359,665 ..."

this is similar to Issac-Newton's [1665] sequence:
http://www.oughtred.org/jos/InExperimentsWhereSenseIsJudge_ IsaacNewtonsTonometerAndColorimeter.pdf
see there on page: 11
"  x= ... 12, 20, 24, 25, 29, 36, 41, 51, 53, 59, 60, 100, 120 , 612" :=306*2

The original is available in facsimile under:
