what is truncated solid

Truncation is an operation in any dimension that cuts polytope vertices, creating a new facet in place of each vertex). In geometry, the term "truncated solid" refers to a solid that has undergone truncation. For example, a truncated cube is an Archimedean solid that has 14 regular faces (6 octagonal and 8 triangular), 36 edges, and 24 vertices. The operation of truncation can be applied to any polyhedron or polytope, and the degree of truncation can vary). A uniform truncation is a special case where the edges have equal lengths, and a complete truncation (or rectification) is another regular polygon in its dual position). A bitruncation is a deeper truncation that removes all the original edges but leaves an interior part of the original faces).
