# PASCAL programs for identification of Lie algebras Part 1. Radical — a program to calculate the radical and nil radical of parameter-free and parameter-dependent lie algebras

## Description

Title of program: RADICAL Catalogue Id: AALB_v1_0 Nature of problem Given a Lie algebra L with structure constants which are either integers or polynomials with integer coefficients, RADICAL determines its radical (maximal solvable ideal) and nil radical (maximal nilpotent ideal).
