Arthur O'Dwyer ced3bbcad4 Qualify calls to format 
C++20 introduces `std::format` and we `using namespace std`,
so some of these would be ambiguous in C++20.

Raw Blame History

/**
* This program was used to generate the rule tables in apeirodic-hat.cpp.
*
* Some data was generated by this program itself, based on manual keyboard+mouse control.
* Some of minor manual control tools have been removed, but the process was as follows:
*
* * Run with `-symbol "12,6,4" -dual -canvas 101010 -smart 1 stamplen=0` and draw the hat shape, the table output is hatcorners
* * Place hats into clusters as shown in the paper, obtaining the table hats[0]
* * Place clusters into superclusters as shown in the paper, obtaining the table hats[1]
* * Repeat for hats[2], hats[3], hats[4] and hats[5] (the paper does not specify precisely the coordinates to arrange the clusters; but we can multiply the previous hats by scaling factor
* * for an approximate, and fix manually so that it matches)
* * 'CON Lx' lines state the rules deduced; the rules should be the same for L1 and L2 (except the matrix codes returned by matcode), so we conjecture that this set of rules is complete
* * Fill the table `hatid` to declare the correspondence between L1 and L2 matrices
* * Run again, and we get rules (prefixed by RULE1 and RULE0)
