We just had a thread "Mathematical Greek Alphanumeric Symbols" about

this, starting 2005/05/14. Perhaps you mean that the missing forms

are:

MATHEMATICAL SANS-SERIF

MATHEMATICAL SANS-SERIF ITALIC

The upright SERIF forms can use the regular Greek, as one does with

the Latin letters. For the other forms, the rule is that they should

be usable, in principle, side by side, to denote semantically

different mathematical objects. Most pure math use the SERIF form

only (as the original TeX fonts). In engineering, the SANS-SERIF

appears (or so, I have a vague memory thereof). But it is unclear

that SERIF and SANS-SERIF are used side by side. If they are not,

then they are to be considered different styles, and should handled

by a font change.
