I've been working on the Compact FEN converter/encoder/decoder routines. A side effect of the testing shows that of the 96,400,068 positions of unique(7), there are exactly 26,633 (ca. 0.0276%) checkmates.

Sums of products

Each of the 96,400,068 unique(7) positions has an occurs attribute. This is an integer which gives the number of times the position occurs among the perft(7) tree terminal nodes. When a perft(7) subtotal for the position is calculated, this subtotal is multiplied by the occurs attribute to give the product for the position.

For unique(7), the value of occurs ranges from 1 to 2600 with a mean of about 33.

The sum of all the perft(7) products for the unique(7) set gives the value of perft(14).

At present, Symbolic (using 128 bit hashes) has processed more than 12,000,000 of the unique(7) positions (work units 000-097 099-104 106-108 110-118 120 122 124 126 964). The sum of products for these is 786,151,906,308,759,975

Ankan's program has processed 40,000,000 positions (using 64 bit hashes).

For work units 400-499, the sum of products is 4,980,591,043,086,812,364
For work units 500-599, the sum of products is 5,584,415,073,949,654,908
For work units 600-699, the sum of products is 7,757,315,049,848,521,464
For work units 700-799, the sum of products is 8,842,605,450,915,113,968

I need to get 128 bit arithmetic running before calculating the grand total sum of products, estimated to be about 6.1*10^19.
