This was the most confusing thing, as Olive doesn’t say. I played around until I got 14 bands of cardinality 10:
Center Hz, range (all rounded here for simplicity)
B1: 114, (96,136]
B2: 161, (136,192]
B3: 228, (192,271]
B4: 322, (271,383]
B5: 456, (383,542]
B6: 645, (542,767]
B7: 912, (767,1085]
B8: 1290, (1085,1534]
B9: 1824, (1534,2169]
B10: 2580, (2169,3068]
B11: 3648, (3068,4338]
B12: 5159, (4338,6135]
B13: 7296, (6135,8676]
B14: 10318, (8678,12270]
Where 114 is the only manual aspect.
Next center frequency: frequency • 2^(1/2)
Start frequency: next cell up from center frequency / 2^(1/4)
End frequency: center frequency • 2^(1/4)
I hope you mean [100,12000]

Now, If I instead create bands starting at 20Hz or ending at 20kHz (both are different), it would be 15 bands.
If Olive meant having the closest to 100,12kHz as the center frequencies, the closest version would be creating bands ending at 20kHz.
However, going by [the formula here on page 31](
https://www.princeton.edu/3D3A/Publications/Boren_ICAD2015_HPEQColoration.pdf), 14 bands total seems correct.
