Some weeks ago, a strange request occured on the net for a Capital greek
Epsilon'', which looks like the letter Open E'' in the african fonts (fc).
However, today I came across a reference for its use in math:

It is used to denote elements of a Grassmann algebra in:
J. F. Cornwall, Group theory in Physics Vol. III, Academic Press, London 1989
on page 7 ff.

It occurres in the upright version.

Yours, J"org Knappen.
