How does the Memphis-Misraim Rite differ from other Masonic rites?

The Ancient and Primitive Rite of Memphis-Misraim is distinguished principally by its extensive scale, comprising ninety-five degrees in total 1. Starting with the three Craft degrees, its system is structured into three series, having undergone various rearrangements and renamings over time 1. Historically, the system arose from what were originally two distinct rites—the Rite of Memphis and the Rite of Mizraim—among the many specialized rites that emerged in eighteenth- and nineteenth-century European Freemasonry 1.

In its governing documentation, the Rite framed itself as universal and open to any Master Mason in good standing under a constitutional Grand Lodge who holds to the Fatherhood of God and the Brotherhood of Man 1. In terms of contemporary recognition, the Ancient and Primitive Rite of Memphis-Misraim sits outside the pale of regular English Masonry and is classified as irregular, as a paper read before Quatuor Coronati Lodge notes.
