d is a decimalpoint, or better called a "6-base-bracket". The message OQ101QOPd1dPOQ101QO can be translated to 1/10 = 0.1 (A-F replaced with 0-5, O means reciprocal, P equals, Q number). The OQ101Q that appear at both ends is 1/10, the inner d1d is 0.1 The following lines of the maessage are transalted in the same way. Q2QLd2dLOQ101QO contains d2d for 0.2 and means 2*1/10=0.2. OQ3QOPd2dPOQ3QO is 1/3=0.2 (correct if base 6!). The next line OQ10001QOPd101dPOQ10001QO contains the number d101d and is in our notation written as 0.01 (inside out!), thus the given equation is 1/100=0.001. The last to lines in the first d-block are for short 1+1/100=1.01 and 1/10+1/100 = 0.11. The last lines of the message have use again the d for calculating with sin and cos. Somebody else wrote that g is similar to pi or another circle related constant. I see g simply as brackets for sin and cos (k and h resp). The periods for sin and cos are then 1000. -Derik.
