That you for the Mark Twain (Death on the Missisliffi: Huckleberry Finn in Finnegans Wake) reference for R³ which I think is his allusion to the Three R’s of Reading Writing and Arithmetic. Gotta love American colloquialisms !!! I do enjoy multiple entendre. The Cubing of the sphere the squaring of the circle is also implied (The Cube the Coach with the sex insides) . Great mystical contemplations. Lots of fun ! There are more allusions and the number continues to grow with reading and reflection.
No reference to Buddhism in the Greek accounts? Possible Alexander’s exploits made room for the explosion of Buddhism after he left. Check dates of inception and cross cultural pollination fertilization . Things always take time to grow to fruition. Cultural movements and conveyances included. Follow your rational logical Train of thought.

“The three “R”s (as in the letter R) are three basic skills taught in schools: reading, writing and arithmetic (usually said as “reading, writing, and ‘rithmetic”). The phrase appears to have been coined at the beginning of the 19th century.
The term has also been used to name other triples
The skills themselves are alluded to in St. Augustine’s Confessions: Latin: …legere et scribere et numerare discitur ‘learning to read, and write, and do arithmetic’.
The phrase is first attested as a space-filler in “The Lady’s Magazine” for 1818. While it is sometimes attributed to a speech given by Sir William Curtis circa 1807, this is disputed. An extended modern version of the three Rs consists of the “functional skills of literacy, numeracy and ICT. (Information and communications technology).”
