| Aug 22, 2016 at 20:44 | comment | added | DavidC | I was able to find 12 sampling points that are sufficient for distinguishing, hence identifying, all of the 36 characters. | |

| Aug 21, 2016 at 6:10 | comment | added | DavidC | Not by moving them around, but instead by using key sampling points to "divide and conquer". 5 bits or points are sufficient to uniquely identify, say, half of the characters. At least 5 more bits would probably be sufficient for all. This would likely save some space, but I'm not inclined to follow it through. | |
| Aug 21, 2016 at 5:27 | comment | added | Sparr | Did you attempt to minimize the number of sampling points by moving them around? | |
| Aug 21, 2016 at 5:14 | comment | added | DavidC | Nice tips and careful reading. Thanks. | |

@DavidC Also, it appears as if some whitespace snuck through to your golfed code, and I count 571 bytes without it. Additionally, some functions can be converted to infix form. x[[All,2,1]] can be replaced with x[[;;,2,1]]. Flatten[x,1] is equivalent to Join@@x, and Flatten[#,1]&/@x is equivalent to Join@@@x. There are a few other minor optimizations that can be done. The 551-byte code after these golfs.

| Aug 20, 2016 at 22:08 | comment | added | DavidC | @LegionMammal978, your suggestion led to a shortening of the code by over 100 bytes. I now understand better how Mathematica handles bases. | |

@DavidC Seems like SE messed it up; try replacing {1118623, 2518818, ..., 16645599} with this.
