By now they were all sitting upon the rug and between them creating a monumental group of unusual grandeur.
(M. Peake; Titus Groan; By Gormenghast Lake)
Should I read it as: '[...] and creating a monumental group of unusual grandeur between them.'?
If so, then how would the phrase change if we removed 'between them'?
Thank you Rover_KE.
I meant if we removed it completely from the sentence.
