The expansion may be obtained by expanding m in ordered 
elementary affinors. 
Also the expansion in non-reducible covariant forms (principal 
theorem B) can be obtained for this most general case by expanding 
P . . 
m with respect to non-reducible covariants. Then the determinants 
of n rows that occur in the expansion of the form generally have 
only an ideal meaning and therefore the non-reducible forms 
occurring in each term have only an ideal significance too. The 
terms themselves however keep their non-ideal significance and are 
found by taking together definite groups of terms from the expansion 
in elementary forms of the first kind.
