  "Description": "Methods to deal with the free antiassociative algebra over\nthe reals with an arbitrary number of indeterminates.\nAntiassociativity means that (xy)z = -x(yz).  Antiassociative\nalgebras are nilpotent with nilindex four (Remm, 2022,\n<doi:10.48550/arXiv.2202.10812>) and this drives the design and\nphilosophy of the package.  Methods are defined to create and\nmanipulate arbitrary elements of the antiassociative algebra,\nand to extract and replace coefficients.  A vignette is\nprovided.",
