# findHeft -- find a heft vector for a list of degrees

## Synopsis

• Usage:
findHeft( x, DegreeRank => ... )
• Inputs:
• x, a list, a list of multi-degrees, each of which is a list of integers of length r
• Optional inputs:
• DegreeRank => an integer, default value null, an integer, r, say
• Outputs:
• a list of integers of length r whose dot product with each member of x is greater than zero, or null, if there is none

## Description
