User blog comment:PsiCubed2/CURRENT VALUE OF PEGG/@comment-32697988-20170908190822

I am working on a spreadsheet that calculates PEGG value automatically given n value. The value of PEGG will be shown in 6 notatons here and SGH and mashimo scale. The spreadsheet can be found here. However, I can't find the definition for PGN (Psi's Geometric Notation). Where s the definition for PGN?
