A comprehensive analysis of centrality dependence of event-by-event fluctuations of pseudo-rapidity multiplicity combination in terms of strongly intensive quantity has been carried out in 22Ne-emulsion interactions at 4.1 AGeV/c. The ensemble of events has been categorized into four centrality classes based on the total charges or sum of the charges of non-interacting projectile fragments (Q). Notably, significant fluctuations in pseudo-rapidity are observed across different centrality ranges. Strongly intensive quantity increases with decreasing centrality while
increases weakly with decreasing centrality up to Q = 4. Our study reflects that change in the strongly intensive quantity
and
does not depend on the number of analyzed events in each class. Experimental results are compared with the analysis of MC-RAND events.
