Question

Find the keyword and plaintext of the following Playfair cipher showing all neccessary work:

NC GM RN UQ TO LK ZQ CT PT QN TL FQ NC TW NQ IO AI GE LM IO

IL QF EK QN HD DX CL GA IL TA HP NU XA IL SG OV BO AG KH TM

TQ LM RT PN GE XT NC KG TB IO MT

(The title is "About Ciphers" and there is a tip "ng and solving"(ng an ds ol vi ng) which lines up with IL TA HP NU XA IL in the cipher since the ng's repeat which follows the IL's repeating; however, I have not been able to combine the combinations that result from ng = IL, an = TA, ds = HP, and so on)
