how to collect similar equation and find all of them

Hello dear friends

i would like to ask you how to callect some equation which involves pluse and mines between 5000 symbolic equation as follows

aknalmamianjaiebkeblj + aknalmamianeaijbkjble - aknalmamianeaijbkeblj + aknalmamjaniaiebkjble - aknalmamjaniaiebkeblj - aknalmameaniaijbkjble + aknalmameaniaijbkeblj + akialmamnanjaiebkjble - akialmamnanjaiebkeblj - akialmamnaneaijbkjble + akialmamnaneaijbkeblj - akjalmamnaniaiebkjble + akjalmamnaniaiebkeblj + akealmamnaniaijbkjble - akealmamnaniaijbkeblj - aklalnamianjaiebkjbme + aklalnamianjaiebkebmj + aklalnamianeaijbkjbme - aklalnamianeaijbkebmj + aklalnamjaniaiebkjbme - aklalnamjaniaiebkebmj - aklalnameaniaijbkjbme + aklalnameaniaijbkebmj +akealmamnanjbkeblibij - akealmamiaijbknbljbne + akealmamiaijbknblebnj + akealmamiaijbkjblnbne - akealmamiaijbkeblnbnj - akealnaniaijbkmbljbme + akealnaniaijbkmblebmj + akealnaniaijbkjblmbme - akealnaniaijbkeblmbmj - aklalnamjanebkibmjbie + aklalnamjanebkibmebij + aklalnamjanebkjbmibie - aklalnamjanebkebmibij + aklalnameanjbkibmjbie - aklalnameanjbkibmebij - aklalnameanjbkjbmibie + aklalnameanjbkebmibij - aklaliamjaiebknbmjbne + aklaliamjaiebknbmebnj + aklaliamjaiebkjbmnbne - aklaliamjaiebkebmnbnj + aklaliameaijbknbmjbne - aklaliameaijbknbmebnj - aklaliameaijbkjbmnbne + aklaliameaijbkebmnbnj + aklaljamnanebkibmjbie - aklaljamnanebkibmebij - CDEakjalebkjble - CDEakjalebkeblj - CDEakealjbkjble + CDEakealjbkeblj - CDEaklalebkjbje - CDEakjajebklble - BDEakebkmbmjbje + CDEaklajebklbje - AFGalmamnanibli - BCGakjbknbnibij + CDFakialebkible - CDFakialebkebli - CDFakealibkible + CDFakealibkebli - CEFaklalnanebke + BDGakiamjbkibmj - BDGakiamjbkjbmi - BDGakjamibkibmj + BDGakjamibkjbmi + BEFaknamebknbme - BEFaknamebkebmn - BEFakeamnbknbme + BEFakeamnbkebmn - BEGakmamnanjbkj - CDGaklaliaijbkj - BEFakmamebknbne - BEFaknanebkmbme - CDFaklalebkibie - CDFakiaiebklble + AEGalnamjblnbmj - AEGalnamjbljbmn - AEGaljamnblnbmj + AEGaljamnbljbmn - BDGakmamjbkibij - BDGakiaijbkmbmj

Have you checked if the collect() function works for your case?

Also check some of the functions here:

Fantastic, dear brother. Could you please assist me? Let me explain my issue. I've discovered that all terms of 7 by 7 detriment of a particular matrix are only symbols, therefore I know that many of the results are the same or have been repeated. I'd like to collect all of the terms that are similar, even if they aren't exactly the same. For example, all of the outcomes are the same. a {12}*a {34}*a {45}*a {24}*b {12}*b {34}+ .... I know the above equation is repeated more than one times, yet it might appear like this. a 12*a 34*a 45*a 24*b 12*b 34+... = a 34*a 12*a 24*a 45*b 12*b 34+... = a 34*a 12*a 24*a 45*b 12*b 34+... Could you help me with this? Warm regards
