SNEG library is a Mathematica package that provides a framework for performing calculations using the operators of the second quantization with an emphasis on the anti-commuting fermionic operators in the context of solid-state and atomic physics. It consists of a collection of transformation rules that define the algebra of operators and a comprehensive library of utility functions. SNEG library is the foundation of the NRG Ljubljana package, however it can also be used as a stand-alone package.
