+"""
+The `[[8p, 4p − 2, 3]]` Delfosse-Reichardt Generalized `[[8,2,3]]` code is derived from the
+quantum `[[8,2,3]]` code. These codes were introduced by Delfosse and Reichardt in the paper
+*Short Shor-style syndrome sequences* [delfosse2020short](@cite). The parameter `p` specifies
+the **number of blocks** in the code construction.
+
+An `[[16, 6, 3]]` Delfosse-Reichardt Generalized `[[8,2,3]]` code from [delfosse2020short](@cite).
