Nameable 13-limit

13-exact-limit intervals with numerator-denominator < 3 are:

13/12, 14/13, 26/25, 27/26, 40/39, 65/64, 66/65, 78/77, 91/90,
105/104, 275/273, 144/143, 169/168, 196/195, 325/324, 351/350,
352/351, 364/363, 847/845, 625/624, 676/675, 729/728, 1575/1573,
1001/1000, 1716/1715, 2080/2079, 4096/4095, 4225/4224, 6656/6655,
10648/10647, 123201/123200

The remarkable 123201/123200 might be named the chalmersia, since John
Chalmers is presumably the first to see it.
