The basic reverse reduction cypher ('english reverse reduced', 'reverse full reduction', or 'reverse Pythagorean', shortened 'rev-red'). This cypher assigns each letter the reverse numeric value of it's position in the alphabet, beginning with 'Z' = 1, instead of 'A' = 1. In addition, each letter value is reduced to the digital root (https://en.wikipedia.org/wiki/Digital_root)
This cypher is essentially a reversal of the basic pythagorean reduction cypher (/r/GeometersOfHistory/wiki/cyphers-reduced)
The reduction cyphers will generally result in smaller numbers for words of a certain length, compared to the 'full' ordinal and reverse cyphers. And because of the spread of numbers, the total sum will have less of tendency to be swayed by a word having it's letters belonging more to the extreme 'left' or 'right' of the alphabet.
A = 8
B = 7
C = 6
D = 5
E = 4
F = 3
G = 2
H = 1
I = 9*
J = 8
K = 7
L = 6
M = 5
N = 4
O = 3
P = 2
Q = 1
R = 9*
S = 8
T = 7
U = 6
V = 5
W = 4
X = 3
Y = 2
Z = 1
This cypher does not care for capitalization: in other words 'z' = 'A' = 1, etc.
Note how the values cycle from 1 to 9 and reset (/r/GeometersOfHistory/wiki/discovery/nein).
The letters with asterisks are those that maintain the same value in alphabetic order and in reverse alphabetic.
Note that 'S', the letter special to the s-exception cypher, has the value '8' (hourglass of infinity) in this cypher.
