Sage is free and open software that supports research and teaching in algebra, geometry, number theory, cryptography, etc. Both the Sage development model and the technology in Sage itself are distinguished by an extremely strong emphasis on openness, community, cooperation, and collaboration: we are building the car, not reinventing the wheel.

This web page lists both bugs in Sage and ideas for features to add to Sage. Please help Sage development by posting extensive information about all bugs you know of or find in Sage here, no matter how trivial.

Formatting hint for bug reports

Please use the {{{ and }}} tags to add code snippets and Sage session transcripts. For example:

  sage: 1 + 2


  sage: 1 + 2
