There was a query regarding the correct form of rAjashyAmalA mahAmantra. But there really is no one "correct" form. The correct form is that which is given by Guru and which has an appropriate pramANa in the tantra. The three popular forms currently in use have slight differences:
The chief pramANa for those following dakShiNAchAra is the shrIvidyA sUtra: shatavarNayutA shyAmA [shyAmA mantra consists of 100 letters]. This is when the syllables sarvajanaM mE are used. Vasistha samhitA does mantroddhAra in this way as well.
The other pramANa is of krodha bhaTTAraka who says: ShaShTyaShTatriMshadakSharEshAnIm [shyAmA mantra consists of 98 letters]. This is when sarvaM mE is used. This use is in line with baDabAnala, parA and other tantras.
kalpasUtra says: aShTanavati varNAH [shyAmA mantra consists of 98 letters]. Here, the words amukaM mE [or trailokyaM mE as described by some commentators quoting yAmaLa due to prayogaparatva of the word amuka] are used and the usage is shrImata~NgIshvari instead of rajamAta~NgIshvari.
The above three seem to be the popular forms used by most lineages.
The a~Nga vidyAs for shyAmalA vary based on the tantra followed. We are taught the following:
1. shyAmalA pAdukA
3. laghu shyAmalA
12. jagadra~njinI shyAmalA
When worshipped in ShoDashAvaraNa shrIchakra with parikalpanA of geya chakra within the chakrarAja, the AmnAya nAyikA for shyAmalAvaraNa is sumukhI and samayA is svayamvarA, vighnahArinI is hasantI, mudrAdhiShThAtrI is trailokyamohinI, Asana devatA is vidyunmAta~NgI and balidevatA is ucChiShTa bhairava. These are the six deities in the parichAraka gaNa. Together, they form 18 devatas known as shyAmalA kula.
