Yes, you behind the bikesheds! Stand still laddy!
"Strangelets – a "a totally new form of matter" comprising three quarks (u, d and s), as opposed to our modest earthly matter, which has only two quarks (u and d)."
Strangelets have a "strange" quark, so hadrons (3-quark units) like [up, down, strange] or mesons (2-quark units) like [up, strange] belong to that set.
Bog standard low-energy matter as we encounter everyday uses up and down exclusively so hadrons like the neutron [up, down, down] or mesons like [up, down] belong to that set.
