== Truncation of wedgies ==

A useful operation to perform on any multivector, including wedgies, is truncation of the wedgie to a lower prime limit. This in effect sets all the basis vectors of a p-limit wedgie which are greater than q, the prime limit being truncated ~~to,~~ to zero. An algorithm to produce the truncation is to list the r-subsets of the primes to p in alphabetical order, and add the corresponding coefficient to the list of the q-limit truncation if and only if the maximum prime in the r-subet is less than or equal to q. Truncating a wedgie can lead to a non-wedgie if the GCD of the coefficients is greater than one; this means that in the lower limit, [[Wedgies_and_Multivals|contortion]] has appeared.

A useful operation to perform on any multivector, including wedgies, is truncation of the wedgie to a lower prime limit. This in effect sets all the basis vectors of a ''p''-limit wedgie which are greater than ''q'', the prime limit being truncated to zero. An algorithm to produce the truncation is to list the ''r''-subsets of the primes to ''p'' in alphabetical order, and add the corresponding coefficient to the list of the ''q''-limit truncation if and only if the maximum prime in the ''r''-subet is less than or equal to ''q''. Truncating a wedgie can lead to a non-wedgie if the GCD of the coefficients is greater than one; this means that in the lower limit, [[Wedgies_and_Multivals|contortion]] has appeared.
