FWIW CoinJoin protocol on Wasabi Wallet 2.x create varied amount of output.
So, there are 79 denominations from 0.00005000 BTC up to 1374.38953472 BTC.
I see that the denominations are quite arbitrary:
The standard denominations are: 5000, 6561, 8192, 10000, 13122, 16384, 19683, 20000, 32768, 39366, 50000, 59049, 65536, 100000, 118098, 131072, 177147, 200000, 262144, 354294, 500000, 524288, 531441, 1000000, 1048576, 1062882, 1594323, 2000000, 2097152, 3188646, 4194304, 4782969, 5000000, 8388608, 9565938, 10000000, 14348907, 16777216, 20000000, 28697814, 33554432, 43046721, 50000000, 67108864, 86093442, 100000000, 129140163, 134217728, 200000000, 258280326, 268435456, 387420489, 500000000, 536870912, 774840978, 1000000000, 1073741824, 1162261467, 2000000000, 2147483648, 2324522934, 3486784401, 4294967296, 5000000000, 6973568802, 8589934592, 10000000000, 10460353203, 17179869184, 20000000000, 20920706406, 31381059609, 34359738368, 50000000000, 62762119218, 68719476736, 94143178827, 100000000000, 137438953472 sats.
Why are many arbitrary numbers included in the denomination sizes?
