### Problem Description
At present the only two DFT's available for the symmetric group algebra are the seminormal basis and modular DFT. Neither of these are unitary transformations.
### Pr…

Hi all,
I'm starting to rewrite some of our AT1.3 pass-methods to AT2.0:
(A). A linear version of IdTable, It is defined by 4 parameters, dx'/dx, dx'/dy,dy'/dx and dy'/dy, it is useful to fit I…
