polydrafters can contain two types of holes
Tp 1 Tp 2
These are two representations of the same piece
polydudes are polydrafters without 30 deg angles, without holes and which are
not narrower then 1/4 triangle edge.
So these are not polydudes.
Epieces I call polydudes which are not narrower then 1/2 triangle edge.
So these are not Epieces
|Polydrafters||Polydrafters hole tp.1||Polydrafters hole tp.2||Polydrafters no holes||Polydudes||Epieces|
The description of file format is here. ( I am sorry for another new file format )
For alternative Eternity I decided not to use
- polyiamonds ( 854 - 12 = 842)
- symmetrical pieces ( 842 - 71 = 771 )
- grain-ambiguous piece ( 771 - 1 =770 )
Remain 770 pieces
I now that the numbers are different from results of Brendan Owens at www.mathpuzzle.com . This is probably due to different definitions or bugs. The bold numbers agrees with his results.
