ZerosToFlagZeros from BinaryWord ​

The word whose reverse complement, prepended, has as many occurrences of 10 as this has zeros.

BinaryWord → BinaryWordbijectioninverse

FindStat's Mp00268, the inverse of FlagZerosToZeros.

Called as CombinatorialMap(x, "ZerosToFlagZeros"). The head's page has its examples.

Properties

Transport a statistic

Pick a statistic on BinaryWord. Its distribution over the images of BinaryWord at each size is computed, and compared with the 59 statistics on BinaryWord: those that share it are the ones the map sends it to, as far as the sizes computed show.

zeros to flag zeros

Matched by value: our map agrees with FindStat's image on each of the 126 rows of size at most 6 we can read (0 unread; its table has 1200 rows).

BijectionGraded mapas FindStat records them, checked by FindStat's contributors.

Return a binary word of the same length, such that the number of occurrences of 1010 in the word obtained by prepending the reverse of the complement equals the number of 00s in the original word.
