Biquadpentquadral Logarithmic Circle

'Biquadpentquadral' is the Systematic Dozenal Nomenclature for two to the twelfth power as the base, from 'bi-quad-pent-quad(r)' standing for dozenal 2454, which is equal to decimal 4096, octal 10000 and unquadral (=hexadecimal) 1000.

At this size, even the first-level divisions cannot all be depicted in an analogue scale. I have therefore put the thick notches to a different use here: they denote the logarithmic twelfths of the base, namely, 2 to first to eleventh power inclusive. (The linear twelfths are inconspicuous in a logarithmic scale: for example, decimal 341+1/3 is somewhere near the angle 252.5°.)
