By showing a connection between $N$-free and order in the special case when $L_Q \mid N$, where $L_Q$ is the largest divisor of $q^m-1$ with the same radical as that of $Q$, we are able to derive the number of elements in $\mathbb{F}_{p^4}$, $p$ being a Mersenne ...
Variable numbers of full-sized and defective elements were detected, but the full-sized P and KP elements were the predominant classes of elements in all strains. The full-sized P and KP element ratios were calculated and compared with latitude. The northernmost and southernmost Brazilian strains ...

Clusters in systems as diverse as metal atoms, virus proteins, noble gases, and nucleons have properties that depend sensitively on the number of constituent particles. Certain numbers are termed ‘magic’ because they grant the system with closed shells
