Arrgh, no. That would be base 14, and a bogus Greco-Latin hybrid to boot.
We already have a hybrid for base 16, which is bad enough.

Raymond Brown, former teacher of Classics, posted the following table on
 2 binary dimidial dyadic
 3 ternary/trinary tertial triadic
 4 quaternary quartal tetradic
 5 quinary quintal pentadic
 6 senary sextal hexadic
 7 septenary septimal heptadic
 8 octonary octaval octadic
 9 novenary nonal enneadic
10 denary decimal decadic
11 undenary undecimal hendecadic
12 duodenary duodecimal dodecadic
 . .... .... ....
16 senidenary sextadecimal heccaedecadic
20 vicenary vigesimal icosadic

'vicesimal' would be more correctly derived from Latin 'uicesima (pars)' =
1/20. But, tho my dictionary does give 'vicesimal' as an alternative to
'vigesimal', I fear the latter is too entrenched in the language now.

'heccaedecadic' would be /hEksIdI'k&dIk/ and spellt/ spelled 'heccedecadic'
in north America, I assume :)
