Nilpotent SQS-Skeins With Nilpotent Derived Sloops

In [5], Gueizow gave an example of semiboolean SQS-skeins of nilpotent class \(2\), all its derived sloops are Boolean “or” of nilpotence class \(1\). In this paper, we give an example of nilpotent SQS-skein of class \(2\) whose derived sloops are all of nilpotence class \(2\). Guelzow [6] has also given a construction of semiboolean SQS-skeins of nilpotence class \(n\) whose derived sloops are all of class \(1\). As an extension result, we prove in the present paper the existence of nilpotent SQS-skeins of class \(n\) all of whose derived sloops are nilpotent of the same class \(n\); for any positive integer \(n\).
