# betti(Ideal) -- gives the degrees of generators.

## Synopsis

• Function: betti
• Usage:
betti I
• Inputs:
• Optional inputs:
• Minimize => ..., default value false, minimal betti numbers of a non-minimal free resolution
• Weights => ..., default value null,
• Outputs:
• , a diagram showing the degrees of the generators of the modules in C

## Description

The output is the degrees of generators and relations of the quotient of the ambient ring by the ideal.
