THE LOGIC FOLLOWED HERE IS:

A  → (+3) → A

B → (+4) → S

R  → (INTERCHANGE WITH FOURTH) → O

O → ((INTERCHANGE WITH IIIRD) → R

A  → (+3) → D

D → (+4) → G

AND

A  → (+3) → D

C → (+4) → G

C  → (INTERCHANGE WITH FOURTH) → E

E → ((INTERCHANGE WITH IIIRD) → C

S  → (+3) → V

S → (+4) → W

SIMILARLY

A  → (+3) → D

G → (+4) → K

E  → (INTERCHANGE WITH FOURTH) → N

N → ((INTERCHANGE WITH IIIRD) → E

C → (+3) → F

Y → (+4) → C
