    "abstract": "Considering massless $u$ and $d$ quarks, and massive (150 MeV) $s$ quarks in\na bag with the bag pressure constant $B^{1/4} = 145$ MeV, a colour-singlet\ngrand canonical partition function is constructed for temperatures $T = 1-30$\nMeV. Then the stability of finite size strangelets is studied minimizing the\nfree energy as a function of the radius of the bag. The colour-singlet\nrestriction has several profound effects when compared to colour unprojected\ncase: (1) Now bulk energy per baryon is increased by about $250$ MeV making the\nstrange quark matter unbound. (2) The shell structures are more pronounced\n(deeper). (3) Positions of the shell closure are shifted to lower $A$-values,\nthe first deepest one occuring at $A=2$, famous $H$-particle ! (4) The shell\nstructure at $A=2$ vanishes only at $T\\sim 30$ MeV, though for higher\n$A$-values it happens so at $T\\sim 20$ MeV.",
