Skip tooth chain

[Fv2]

I need a skip tooth chain, apparently I sold the only one I had.
Not sure how many links I need, or how to figure that out. But if anyone has one for sale, let me know.
Thanks.

skip tooth chain length formula:

A=distance from rear axle to center of crank bb. (in inches)
C=number of teeth on cog
S=number of teeth on sprocket.

length = Ax2 + C/2 + S/2

Slide the wheel all the way back to get the longest possible length.
Slide the wheel all the way forward to get the shortest possible length.
Skip tooth chains are to be considered 1" pitch so a workable length needs to be a whole number between the shortest & longest.

if the wheel & sprocket are original, look for the gouges in the rear dropouts for the original position and measure from there.

I'm not sure how wheel size is relevant, but 26.

This calculation gets me 108.
But other calculations are Ax2 +C/4 + S/4 +1 and that gives me 157.

The average length from axle to BB is 20" with a 24 tooth sprocket and 10 tooth cog.
