Need help to solve this cipher..... Hi everyone, ive been given the following cipher: HSRFB YEIOG MVMMA RDETD AEOSE UIOII GHRAL BLIPE DIEJL TOBOR PALBT AWIAP TEATO DOTDU DWRIL KYUOI EYOEO YAIYN FINSH LSWRS FIENU ROWRI JSLKT SYMAL NWTTE OKNIL EAKIE NEEDN EAWTJ SSUEI EHMVE IMTES IADLI LEAKH MGCOD SRNIA ILWSE NEDET VLTFL DETAO OLWNE DTEAS IIHCD BCKDN CYHUN KEIGH HNLBC EIRFG N (6 lines, 8 blocks on each line, 5 characters in each block, except last line having letter N standing alone) and no hint is given. ive tried to do frequency analysis, it shows that letter E appears the most (29 times), then I (25) and then L,A,T,O. So i guess it is unlikely to be substitution cipher. But then i dont know what to do next,ive tried transposition, but it didnt show any useful message. could any one give me some advice to solve this cipher? thanks, PS: i reckon the last letter N,which stands separately from the block, could be the key,but i cant figure out how to use it.
